Camshaft Journal Wear
Check camshaft journals and camshaft housings for
pitting, scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder
head with housing. Never replace cylinder head without
replacing housings.
Check clearance by using gauging plastic. Checking
procedure is as follows.
1) Clean housings and camshaft journals.
2) Make sure that all tappets with shims are removed
and install camshafts to cylinder head.
3) Place a piece of gauging plastic to full width of
journal of camshaft (parallel to camshaft).
4) Install camshaft housing.
5) Tighten camshaft housing bolts in such order as
indicated in figure a little at a time till they are
tightened to specified torque.
NOTE
Do not rotate camshaft while gauging plastic
is installed.
Tightening torque
Camshaft housing bolt (a): Tighten 11 N
⋅
m (1.1
kgf-m, 8.0 lb-ft) by the specified procedure
6) Remove housing, and using scale (2) on gauging
plastic envelop (1), measure gauging plastic width at
its widest point.
Journal clearance
If measured camshaft journal clearance exceeds
limit, measure journal (housing) bore and outside
diameter of camshaft journal. Replace camshaft or
cylinder head assembly whichever the difference
from specification is greater.
